Definitions
- the invention relates to a method for manufacturing a multi-layer elastic fabric according to Preamble of claim 1 and a multilayer elastic Flat structures according to the preamble of the claim 10th
- a multilayer elastic fabric is already known from EP 0 321 980 A. It includes an inelastic one Fiber or filament layer and an elastic layer.
- the inelastic layer becomes elastic with the stretched Layer by spacing through a thermal bonding process Connections connected and then the whole Flat structures relaxed.
- the inelastic throws itself Layer of fibers or filaments between the connection points perpendicular to the surface plane. When stretching the The structure reduces the posing until the fibers of the fiber or filament layer parallel to the surface plane have aligned.
- DE 42 43 012 A1 is a multi-layer elastic Fabric known, in which an elastic and an inelastic layer on spaced apart Connections connected and then stretched become. The elastic position arises after the first Stretch back while the inelastic position is a permanent one Undergoes stretching and between the joints poses perpendicular to the surface plane. For the inelastic Only fiber materials are considered, that have a high permanent elongation.
- EP 0 432 763 A1 The closest prior art is EP 0 432 763 A1. From this it is known to be an elastic Film with a pre-stretched nonwoven at joints to connect while stretching the elastic is in a tense state. Therefore arches between Joints of nonwoven and film when relaxed Film the nonwoven.
- the invention has for its object a method for the production of a multilayer elastic fabric to specify and a multi-layer elastic fabric to create that in an elongation direction the path reserve of their inelastic position by aligning of fibers in the plane of the surface.
- This task is carried out in a method according to the generic term of claim 1 and a multi-layer elastic Flat structure according to the preamble of claim 10 by the characteristics specified in the license plate solved.
- the invention is a multi-layer elastic sheet from at least one elastic layer from one Film, a film or a fiber structure and at least one with the rubber-elastic layer at permanent connection points bonded solidified non-elastic fiber fleece for Provided.
- the inelastic nonwoven layer is in front pre-stretched from their connection with the rubber-elastic layer and the inelastic nonwoven layer in the pre-stretched state connected with the rubber elastic layer.
- the fibers of the inelastic nonwoven fabric layers are essentially in the direction aligned with the direction of pre-stretching. Between the inelastic nonwoven layer and the rubber-elastic layer a dehesive layer is partially arranged, whereby a area left of the adhesive layer between the rubber-elastic layer and the nonwoven layer a permanent Liaison.
- the solidified inelastic Nonwoven ply By pre-stretching the solidified inelastic Nonwoven ply essentially align fibers Direction of the pre-stretching direction and keep this alignment even after connection with the rubber elastic Location if it is relaxed.
- An elasticity of the composite material in the direction transverse to the direction of pre-stretching is made possible by the fact that Fibers between the joints with the rubber elastic Deflect the position like a scissor gate to let. Depending on the elongation, they adjust the Fibers from the original direction along the pre-stretch direction then in the direction of expansion.
- the Path reserve is here from the deflection of the fibers in related to the surface plane. The layer thickness and the surface profile the inelastic situation change Not.
- the rubber elastic can Location before connecting with the inelastic Nonwoven layer in the direction of the pre-stretching direction the inelastic nonwoven layer stretched, in the stretched Condition with the pre-stretched inelastic nonwoven layer connected and then the resulting multilayer Fabrics can be relaxed.
- This fabric is stretchable in two dimensions, namely on the one hand in the pre-stretching direction of the inelastic Nonwoven layer and on the other hand across. there the fabric draws the path reserve of its inelastic Position when stretching in the direction of pre-stretching the peaks of the fibers between the joints and transversely from the orientation of the fibers in the Surface plane.
- the connecting surface of the rubber elastic Layer and / or the inelastic nonwoven layer with a partial under exclusion provided connecting points formed dehesive Provide coating Using a bonding process then a full-surface connection between the rubber-elastic layer and the inelastic non-woven layer generated. Finally, areas of the full area Connection with subsequent expansion in the transverse direction to the direction of pre-stretching and additional while connecting to the stretched inelastic Nonwoven layer in the direction of the pre-stretching direction stretched rubber-elastic layer with subsequent Relaxation except for permanent connection points solved again.
- the advantage of this measure is that in the bonding process, the z. B. by thermal bonding or ultrasonic bonding can be carried out, a uniform Pressure on the elastic rubber layer and the inelastic nonwoven layer can be exercised. Damage caused by evasive pressures of the material to the sides and thus to one Reduction of the layer thickness at the intended connection points would therefore not occur. This is especially true if the elastic layer through the Elongation in cross-section reduced during the bonding process is.
- the inelastic nonwoven layer can be along or across Production direction are pre-stretched. Is preferred a pre-stretching along the direction of production, because on the one hand this facilitates the pre-stretching, on the other hand - in the absence of an additional one Elasticity in the direction of production - the transport in a production line and further processing, since the material is not in the direction of production gives way.
- the inelastic nonwoven layer can be up to at least 50% of the maximum elongation at break.
- the inelastic nonwoven layer can be pre-stretched so that they are longitudinal when pre-stretched a strength ratio along the direction of production too transverse from 0.8 to 1.2 to 20 to 3 and with pre-stretching a strength ratio across the production direction transverse to longitudinal from 0.8 to 1.2 to 20 to 3.
- the inelastic nonwoven layer can be the rubber elastic Position before their connection with the inelastic nonwoven layer stretched by up to 150% of their original length become.
- the nonwoven layer is inelastic, it comes after the Relaxation of the rubber-elastic position then leads to a posing of fibers that are longer by the amount of this stretch than the distances between the connection points.
- the adhesive coating can be provided with dyes or color pigments become. This allows a color design reach without printing on the fabric got to.
- the adhesive coating can be between 5 - 90% of the bonding area cover. In this way, the Distances of the intended connection points and their Change the surface so that the elasticity changes can influence.
- This layer can have a multilayer structure have, the serving as a connecting surface Layer one lower by at least 20 ° Celsius Has melting point than the other layer.
- the nonwoven layer is only superficial a connection with the rubber-elastic layer there can be prevented by the different melting points can that also the sub-layer with the higher Melting point softens and the fibers of the nonwoven layer penetrate into this sub-layer.
- it can be used as a connecting surface serving layer of copolymer raw materials with one of at least 2.5 ⁇ m and the other Layer of elastomeric, polymeric and copolymeric raw materials with a thickness between 8 - 100 microns, preferably between 15 to 80 ⁇ m.
- the rubber-elastic formed as a film or foil Layer heterogeneous and elastomeric, include polymeric and copolymeric raw materials.
- the raw materials mentioned are mixed, but the mixing is not homogeneous, so that the specific adhering to the raw materials Properties, namely rubber elasticity and adhesiveness or cohesiveness are still preserved.
- the fibers can be made from bicomponent fibers exist, the one component by at least 20 ° Celsius lower melting point than the other component having.
- the fiber structure can be made from hetrofil fibers consist of the elastomeric polymers and copolymers Includes raw materials.
- Fig. 1 shows a device for producing a multilayer elastic fabric.
- a fleece layer is first produced in a laying device, which alternatively after the spunbond process or Melt blow molding can be done.
- This is located above the laying belt 20, a nozzle device 22 for the emerging melt, which in the case of a spinning device as a spinning beam and in the case of a meltblowing device designed as an arrangement of meltblowing nozzles can be.
- the nonwoven layer then arrives at a calender roll arrangement 24, by means of the z. B. thermal or ultrasonic bonding the nonwoven layer was consolidated becomes.
- a rubber-elastic film 10 is provided, which runs over a printing roller 30 and with a adhesive layer 14 corresponding to one through the printing roller 30 provided predetermined patterns becomes.
- the applied adhesive layer 14 thereby covers not the entire surface of the rubber-elastic film 10, but leaves open areas that are later permanent connection points 16 serve.
- the stretchability of the multi-layer fabric is also in the direction of pre-stretching, so the rubber-elastic Slide 10 by running at different speeds Transport rollers also in the direction of production stretched. Then the rubber-elastic film 10 with the pre-stretched nonwoven layer 12 brought into contact and passes through a bonding device 32 with smooth heated Rollers. In the bonding process, the rubber elastic Layer 10 and the nonwoven layer 12 on the from the adhesive Coating permanently contacted 14 vacancies, while in the remaining places it is only a temporary one Establish connection.
- Figures 1 and 2 show a top view of a multilayer elastic fabric with pre-stretched inelastic nonwoven layer 12.
- the fibers of the nonwoven layer are predominant in Fig. 2, which shows the relaxed state aligned in the direction of pre-stretching.
- Fig. 2 shows the relaxed state aligned in the direction of pre-stretching.
- the joints 16 shown with the rubber-elastic position.
- the fibers 18 of the nonwoven fabric layer pivot 12 around the connection points 16 as pivot points and are directed from the originally in Alignment orientation more and more in the direction of expansion.
- the swivel angle is relatively small, so that there is no resistance to the stretch and only the properties of the elastic layer that Determine elongation behavior.
- the further the fibers 18 in Direction of elongation the bigger it grows the resistance to further stretching until finally the Path reserve is exhausted.
- An elongation in the direction of stretching becomes a big resistance right from the start opposed. Because the fibers are pre-stretched have increased strength against further stretching, there is also security against overstretching, when the path reserve is exhausted.
- FIGS. 4 and 5 show a section through a multilayer elastic fabric made of an elastic rubber Layer 10 and a nonwoven layer 12.
- the rubber elastic Layer 10 bears a adhesive applied in the form of a pattern Coating 14. This pattern leaves areas free the connection points 16 of the two layers provided 10, 12 serve. At these designated junctions 16 is the rubber-elastic layer 10 with the Nonwoven layer 12 glued or superficially fused.
- FIG. 4 shows the relaxed and Fig. 5 the tense Status.
- the nonwoven layer adheres to this representation 12 on the rubber-elastic layer 10 at the connection points 16, while in the remaining areas, the are provided with the adhesive coating 14, the nonwoven layer 12 takes off and poses.
